Specification of Letters Patent.

Patented Dec. 13, 1910.

Application iled J'uly 25, 1907. Serial No. 385,421.

To all whom 'it may concern:

Be it known that I, ROYAL D. ToMLINsoN, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State oflVisconsin, have invented a certain new and useful Condenser, of whichthe following is a specification.

This invention relates to condensers and comprises improvements in thestructure and arrangement of the parts of jet or barometric condensers,and the objects of this invention are to provide a condenser body ot'simple construction, the parts of which may be readily arranged to suitthe specific needs of any plant, to provide cheap and easily constructedmeans to be disposed within the body of the condenser for insuringrthorough and complete spraying of the water, to provide a system ofpipes so arranged in the condenser body that the air which is drawn oilthrough them may be cooled by the inlowing condensing water, and toprovide a hot well of special construction which is specially adaptedfor use in connection with the discharge pipes leading from et orbarometric condensers supplied with a tail pipe and an overflow pipe.

rlhe drawings which accompany this specification and form a part of thesame and on which the same reference characters are used to designatethe same elements wherever they may appear in each of the several views,show a condenser embodying this invention.

Referring to the drawings,-Figure 1 is an elevation with parts insection; Fig. 2 is a sectional elevation of the head and a part of thetail pipe, drawn to an enlarged scale; Fig. 3 is a plan view of thespray plates; Fig. 4 is a vertical section of the spray plates taken onthe line w-a of Fig. 3; and Fig. 5 isa section of a detail, drawn to anenlarged scale.

Referring to the drawings, the numeral 1 designates a cylindricalcasing, which forms a part of the body proper of the condenser, providedwith the steam inlet 2, this inlet being provided with the deflector 3located within the condenser head, and to the inlet 2 is connected theexhaust steam ipe 4.

The numeral 5 designates the ase of the condenser which is provided withlianges to which are adapted to be connected the flanges of the tailpipe 6 and the flanges of the casing 1.

The numeral 7 designates the top or cap of the condenser, provided withthe water inlet 8, to which the pipe 9 for conveying the condensingwater to the condenser is connected. The top 7 is shown as provided witha flange by which it may be connected with a flange at the upper end ofthe casing 1, though it is to be understood that any equivalent meansfor uniting the casing 1 and the top and hase may be provided, as thespecial fastening means which may be employed form no part of thisinvention. The upper end of the top 7 is open and is provided with aflange to which the dry air pipe 10 is connected. This dry air pipe 10is extended into a receptacle or separator 11 from which the pipe 12leads to the dry air pump 13. The separator 11 is provided with a drippipe 14, which for convenience leads down into and discharges into thehot well 15.

The numeral 16 designates the free discharge pipe of theair pump throughwhich the air which accumulates in the condenser is discharged by thepump into the atmosphere and this pipe is illustrated by the drawings asbeing a'branch of the pipe 17, which is in communication both with thedischarge side of the dry air pump and the pipe 18, which pipe in turnis in communication with the pipe 12 and is extended within the tailpipe 6 where it projects downwardly a short distance and is providedwith ejector orifices.

The valves 20, 21, 22 and 23 are provided by which the discharge of theair from the condenser may be caused in one of several ways. By closingthe valves 21 and 22 and opening valves 20 and 23, the pump 13 willdischarge the air from the condenser into the atmosphere. By closingvalves 21 and 23 and o ening valves 20 and 22, the pump will disc largethe air from the condenser into the tail pipe 6, the back pressure onthe pump being reduced by the vacuum creating power of the water flowingthrough the tail ipe. By closing valves 20 and 22 and opening valve 21,the suction eilect of the water flowing through the tail pipe willwithdraw the air from the condenser, and

this procedure may be adopted either to save the expense of operatingthe pump or to hold a vacuum .if the pump be disabled.

It should be observed that the pipe 17 is led to a sufficient height sothat the water in the condenser will overflow into the overflow pipe 24before it rises to a height where itcould pass into the pump 13 throughsaid pipe 17.

The overflow pipe 24 is shown as provided with an elbow 25 to which apipe 26 may be connected, the pipes 24, 26, and elbow 25 b-eing of sucha size that they can serve as a free exhaust for the engines whenrunning non-condensing, and pipe 26 may be provided with any suitable orpreferred valve arrangement as the stop valve 260 or preferably anordinary form of atmospheric relief valve for permitting such freeexhaust while maintaining the function of the pipe 24 as an overflowpipe when running condensing. Elbow 25 is provided with areduced nipple27 to which is connected the overflow pipe 28 which extends into the hotwell.

As before stated, the numeral 15 designates the hot well into whichextend the overflow pipe 28, the tail pipe 6, and the drip pipe 14,their open ends being water sealed therein, the hot well being providedwith the overflow 29 which may lead to waste or be connected withasecond hot well from which the boilers are fed. The hot well 15isprovided with partitions 30 and 31 which extend from the bottomthereof higher than the outlets of the pipes entering said hot well, thepurpose of these partitions being to prevent any air which may bedischarged through any one of said pipes from ascending into anoth-er ofsaid pipes. These partitions, while preferably being formed aspartitions for cheapness of manufacture, may be replaced by pipessurrounding the lower ends of the pipes which discharge into the hotwell, vand of greater diameter than the same, as barriers will thus beformed which serve the same purpose as the partitions permitting thefree discharge of air and water from a pipe but preventing any airdischarged by one pipe from ascending the open end of an adjacent pipe.

Lugs 32 are provided preferably acent the top of the base upon whichlugs the umbrella 33 is seated, this umbrella serving to spread thewater so that it forms a perfect seal between the steam space 34 of thecondenser and the chamber which is formed by the umbrella and the baseof the pipe 37 being centered by the spider 38 which is shown as clampedbetween the flanges of the head and the dry air pipe 10. This pipe 37,is provided with a collar or step 39 upon which rests the spray plate40, the spray plate 40 in turn support-ing the urn 41, these membersbeing formed separately and slipped into position over the pipe andsimply rest against the collar 39.

The numeral 42 designates an annular dam which is supported upon theflange 43, preferably formed integral with the casing 1, this dam beingin cross section substantially semicircular and affording on its underside a pocket 44 in which air can collect while its semicircular shapein cross section causes the water which enters through inlet 8 to bedistributed `entirely around the circumference of the condenser head andto flow over said dam from all sides down through its central aperture45. The top of the dam is provided with flanged apertures 46, and uponthe flanges of these apertures are seated the pipes 47, upon the tops ofwhich is seated the spider-collector-coupling 48, the pipe 37 beingprovided with apertures 49 in the chamber of this coupling through whichthe air which collects underneath the dam may be drawn out through pipe37 and pipe 10.

The spider 38 located at the upper part of the head 7, permits any airwhich mightaccumulate in the upper part of said head to be withdrawnthrough pipe 10.

rEhe extreme simplicity of the construction illustrated and described isapparent at. a glance. rPhe casing 1, head 7 and base 5 areinter-dependent so that one can be turned with respect to its adjacentelement whereby any specific condition as to the direction of lead ofthe condensing water pipe with respect to the steam exhaust pipe may #bereadily established. Moreover the different parts located within thecondenser proper are simply held in position by being slipped one overthe other and there are no bolts, screws or other fastening deviceslocated within the condenser, consequently the parts may be readily andconveniently removed with the least trouble and expense.

ln assembling the condenser, the base 5 is first set up, then the casing1 is placed upon the base, the proper' direction of the exhaust steaminlet 2 being fixed, the umbrella is then seated on the lugs 32, thepipe 37 seated upon the umbrella, the spray plate 40 slipped over theupper end of the pipe, the urn 41 slipped over the pipe on top of thespray plate, the dam 42 is placed in position, the pipes 47 are. slippedover the flanges ofthe apertures 46, the spider 48 is slipped over thepipe 37 embracing the upper ends of the pipes 47, the top 7 is thenplaced upon the casing 1 giving the proper lead to the inlet 8, thespider 38 is then slipped over the top of pipe 37 and the dry air pipe10 is then connected up. The reverse of these operations is theprocedure for disassembling the condenser.

The spray plate 40 is composed of a hub 400, radially extended arms 401,each ol said arms carrying at the extremity thereof a section 402 of anannular ring, the upper surfaces of these sectors being provided withpyramidal projections 403.

The urn 41 is provided with va hub 404, the cup or receptacle 405 withthe rolling flanges 406, over which the water flows to fall upon thesections 402 between the upstanding guards 407, which guards are placedin the condenser so that they are directly above and radially in linewith the spaces 408 between the sections of the splash plate, theseguards serving to prevent water flowing out of the urn at those placeswhere it would not imninge upon the sections 402.

Referring' to Fig. 5 of the drawings, the pipe 1S is shown as providedat its lower end with the apertures 19 which are vertically elongated,and the end of said pipe is closed by the double cone 500 which isprovided with screw threads 501 adapted to engage with screw threads onthe pipe to retain one end of the cone within the end ot" the pipe 1S.This double cone structure is employed to divert lthe air outwardly fromthe pipe 1S through the apertures 19 into the rater flowing out throughthe tail pipe 6, and the lower end 503 ot' the cone is shaped to conformsubstantially to the lines of flow ot' the water by the end of the pipe18 so that no pocket will exist at this point in which air may collectby escaping from the water in the tail pipe. It is obvious that it' itwere not for this provision of the end 503 of the cone there would be atendency to create a vacuum in a conical space below the end of pipe 18,and air instead of passing down the tail pipe and out with the water,would separate from the -water and ll this space with air.

1. The combination with a condenser casing provided with steam and waterinlets and a tail pipe, of an overflow water pipe to act in conjunctionwith the tail pipe to pre vent flooding of the casing when steam isbeing condensed therein, said overflow pipe having` direct communicationwith the atmosphere, and a valve controlling said communication.

2. The combination with a casing provided with steam a-nd water inlets,of a tail pipe for discharging' the condensing water and the water oi'condensation from said` casing, a dry air pipe leading from said casing,a pump with which said dry air pipe is connected, a second pipecommunicating with said dry air pipe between said pump and the casing,said second pipe being ex tended into said tail pipe and adapted todischarge air therein, said dry air pump being' provided with a.discharge pipe communicating with said last mentioned pipe and beingprovided also with a i'ree exhaust, and valves in said pipes so disposedthat air from the casing may be discharged by said dry air pump eitherthrough the lree exhaust or into said tail pipe, or that air from thecasing may be discharged directly into the tail pipe without passingthrough the dry air pump.

3. The combination with a casing provided with steam and water inlets,`atail pipe and an overflow pipe, of a dry air pipe, a dry air pump withwhich said pipe communicates, and an upwardly extended discharge pipefrom said dry air pump adapted to discharge air into said tail pipe,said discharge pipe from the dry air pump being extended upward to apoint higher than the connection of the overflow pipe with said casing,whereby water from said tail pipe will be prevented from entering thedry air pump.
